WINDOW SILL Filed Jan. 28, 1959 wir Patented Oct. 31, 1939 rAsN'r Oerle WINDOW SILL Paul Morton Keary, Mount Vernon, N. Y. Application January 28, 1939, Serial No. 253,287 e claims. (o1. 72;-98)

My invention relates to window sills and has for one of its objects the provision of a sill structurewhioh can be manufactured and sold cheaply; which will not require up-keep expense, and

which will not become discolored.

Another object of my invention is to provide a window sill structure which can be installed easily and which cannot accidentally become displaced or dislodged.

Another object of my invention is to provide window sill elements of such form that they can readily be applied to steel frame and masonry wall structures, and which, although made in sections, will protect underlying masonry from l5 the weather.

The window sill sections as herein shown and described, are formed of vitrifled clay, but it will be understood that various other materials such as metal or molded plastics can be employed.

In the accompanying drawing Figure 1 is a vface View of a portion of a building containing my window sill structure; Fig. 2 is an enlarged View taken on the line II'-II oi Fig. 1;v Fig. 3 is an enl larged View taken on the line III-III of Fig. 2,

and Fig. 4 is an'inve'rted plan view of one of the sill sections of Fig. 3.A v The brick wall of a building is indicated by the numeral 5 and has a window opening above which a lintel bar 6 is positioned, the numeral 'I indicating the side members of a metal window frame and the numeral 8 the bottom member of the window frame. These elements may be of conventional form well known in the art, and do not in themselves constitute a part of the present invention.

Thesill (at the outside of the window) is here shown as comprising sections 9 and Ill arranged in end-to-end relation, and preferably formed of vitrified clay or salt-glazed vitried tile. It will o be understood that these sill sections can be made of any suitable length, and a desired number of them can be employed in forming a sill.

Each sill section hasr formed thereon an upstanding lip II, downwardly extending flange- 45 like ribs I2 and I3, and a skirt I4, all of which extend longitudinally of the sill elements, and each sill section is further provided with a rib portion I5 that extends forwardly and rear- Wardly. 50 The members 9 and IB are also provided with overlapping wing portions I6 and I'I respectively, these wing portions sloping upwardly toward the rear edge of the sill, and being inclined slightly in a direction toward the mid portionv of the sec- 55 tion 9, so that if -any water seeps between the meeting edges of the sections 9 and II), it will drain along the ledge I6 toward the outermost end thereof, and water will be prevented from draining into the underlying body of ,mortaig where it not only might disintegrate the mortar, 5 but cause disruption through freezing.

The endmost section at the right-hand side of the window will have no wing I6.

The lips II are inserted behind the lowermost flange of the frame member 8; the ribs I2 and I3 10 serve as retaining lugs and to strengthen the sill sections, and the skirts i4 partially overlap the outer face of the wall 5 to protect the same against the weather.

In installing the sill sections, a thick layer ot' 16 mortar I8 (to a depth sufficient to ll the hollow spaces in the sill members) is placed upon the masonry work 5 and the sill sections inserted so that they will occupy the position shown more clearly in Fig. 2. They are pressed rmly down 20 into the mortar IG and caulking material I9 is inserted to seal the joint between the lips II and the member 8, caulking material also being inserted in the crevice at 20, between the sections. Upon drying of the mortar I8, the sill will be 25 held rmly in place and any moisture which accumulates thereon will be drained to the outer face of the wall '5.

The portions I2 andl I3 can, if desired, extend entirely through the mortar i8 and have direct 30 engagement with the upper surface of the brickwork at 5. Also, instead of using the ribs I2 and I3, legs or lugs of relatively small dimension in horizontal section can be employed, and these legs can rest directly upon the brickwork or sim-4 35 ply extend into the thick layer of mortar I8.

I claim as my invention:

l. The combination with a wall having a window opening therethrough, of a sill structure comprising a window sill member having a down- 40 wardly extending rib adjacent to its rear edge,

a downwardly extending rib near its iront` edge, a skirt depending from said front edge, the ribs and skirt extending longitudinally of said member, and a mortar layer normally of greater thickness than the depth of said ribs, on an upwardly-exposed surface of the wall at the window opening, the mortar layer extending'rearwardly of and embedding the first-named rib.

2. The combination with a wall having a window opening therethrough, of a sill structure comprising a window sill member having a downwardly extending rib adjacent to its `rear edge, a downwardly extending rib near its front edge, a skirt depending from said front edge, the

ribs and skirt extending longitudinally of said member, and a mortar layer normally of greater thickness than the depth of said ribs, on an upwardly exposed surface of the wall at the Window opening, the mortar layer extending rearwardly of and embedding the first-named rib, and the sill member sloping upwardly in a rearward direction.

3. The combination with a wall having a Window opening therethrough, of a sill structure comprising a window sill member having a downwardly extending rib adjacent to its rear edge, a downwardly extending rib near its front edge,

a skirt depending from said front edge, the ribs and skirt extending longitudinally of said member, and a mortar layer normally of greater thickness than the depth of said ribs, on an up- Wardly exposed surface of the wall at the Window opening, the mortar layer extending rearwardly of and embedding the first-named rib, and the sill member sloping upwardly in a rearward direction and being provided with an upstanding window frame member.
